Unfortunately, it's all a complicated trap set up by Droz to punish Gomez. Gomez is kidnapped, drugged, and replaced with a double. The double renounces capitalism and praises the party at his festival speech. But then the double is suddenly double-crossed by Droz and gunned down, and Droz blames the murder on Americans and cancels the festival.
Brain Boy uses his mind-reading and controlling powers to figure out the plot, track down and save Gomez, and escape a tank attack by Droz's own power-hungry telepath, Ricorta. He gets Gomez safely back to America.
